North H Bomb

North Korea sharply raised the stakes in its stand-off with the rest of the world Sunday, detonating a powerful nuclear device that it claimed was a hydrogen bomb that could be attached to a missile capable of reaching the mainland United States.

President Donald Trump signaled Sunday that he was not ruling out a retaliatory strike against North Korea in response to its overnight nuclear test, while Defense Secretary Jim Mattis warned.

North Korea has developed a hydrogen bomb which can be loaded into the country's new intercontinental ballistic missile, the official Korean Central News Agency claimed Sunday.

South Korea is in talks with the United States to deploy US strategic assets on the Korean peninsula, a South Korean military official said today, a day after North Korea said it successfully tested a hydrogen nuclear device.

The US and South Korean presidents vowed today to impose the "most powerful and comprehensive" sanctions on North Korea after its globally condemned fourth nuclear test.

China is unlikely to take strong action in response to North Korea's claimed test of a hydrogen bomb, according to experts who say Beijing prefers the devil it knows to the uncertainty that could follow a confrontation.

Japan's defence ministry today deployed three planes to collect possible radioactive material following North Korea's claimed hydrogen bomb test, officials said.

North Korea said today it had successfully tested a miniature hydrogen bomb, which if confirmed, would place it among a small group of countries with such dangerous weapons.
